降落伞充气过程流固耦合方法的数值预测分析
Numerical Prediction Analysis of Parachute Inflation Process Using Fluid-Structure Interaction Method
摘要
Abstract
In order to compensate the lack of traditional empirical methods,the inflating process of a fivering cone parachute in infinite mass condition is simulated based on fluid-structure interaction(FSI) method,and the corresponding aircraft deceleration test is also done.The folded parachute inflating process is simulated by arbitrary Lagrangian Eulerian FSI method.The simulation results are compared with the test results in finite mass condition.It is found that the swinging angle,the projected diameter in fully inflated time and the drag characteristics are consistent with the test results.Moreover,the inflation time and the opening load are affected by velocity greatly.Based on the revised velocity,the predicted inflation time is slightly faster than that in the test,and the opening load is consistent with that in the test.The above indicate that the numerical method based on FSI can predict the parachute inflating performance.关键词
